Instant reefing with Single Line Reef

Single Line Reef is made practical and reliable by Seldén. All you do is ease off the halyard to premarked reefing points and then haul in on the reefing line. The luff and the leech are reefed at the same time. A system of guided blocks inside the boom ensures that the lines do not tangle. The system has a 2:1 gear ratio for effortless reefing, without having to leave the cockpit.

The kit contains:

  • ø10 mm white/blue 32/3 Polyester line for reef 1. 6+ 25 m
  • ø10 mm white/red 32/3 Polyester line for reef 2. 6 + 38 m
  • 2 composite Single Line sliders that run in tracks inside the boom. 
  • 2 PBB60 Single blocks used as turning blocks and fitted to the outboard end 500-016. 
  • 2 reef shackles
  • 2 composite sheaves for your inboard boom end.
  • 1 ø10 mm x 94 mm shaft

Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

Great value!
Color: Ink Black, Size: 2 pack
Really sturdy and a great value for the money. Almost idiot proof when putting it together, too. The drawing is very specific, and everything is really well marked and numbered. This isn’t fine furniture, but it really is a great value for the money!
